OLIVER L. NUNIVILLE'R, 0F FINDLAY, OHIO.

WASHING MACHINE.

Application filed September 19, 1924. Serial No. 738,669.

To all whom it may concern:

Be it known that I, OLIVER L. NUNIVILLER, a citizen of the UnitedStates, residin at Findlay, in the county of-Hancock and S tate of Ohio,have invented a new and useful \Vashing Machine, of which the followingis a specification.

- The device forming the subject matter of this application is a washingmachine, and the invention aims to provide a device of the classdescribed in which the receptacle which carries the dirty clothes israised out of the liquid in a tub and lowered into the liquid in a tub,the clothes being subjected to pressure, yieldably, whilst thereceptacle and the clothes are being raised, novel means being providedfor imparting vertical reciprocation tothe receptacle.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that sort to which the inventionappertains.

\Vith the above and other objects in view which will appear as thedescription pro-- ceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed may be made with in thescope of what is claimed without departing from the spirit of theinvention.

In the accompanying drawings Figure 1 shows in vertical transversesection, a device constructed in accordance with the invention, partsbeing in elevation;

Fig. 2 is a top plan view wherein parts are broken away.

In carrying out the invention, there is provided a frame 1 which may bevariously constructed, depending upon the taste of the manufacturer orthe user. As shown, but not of necessity, the frame 1 includes legs 2connected by a base 3, standards 50 being connected to the upper ends ofthe legs, the standards carrying a support including a platform 5, andcross pieces 6 mounted in the standards and upholding the platform.Retainers, in the form of bars 7, are mounted removably in the upperends of the standards 50. For the support of a wash tub or any otherarticle one of the standards 50 may carry a laterally extended table 8.In general, however, the frame may be made as desired. There is anopening 9 in the center of the platform 4.

A tub 10 is supported on the platform 5 and fits closely between-thestandards 50. The tub 10 has an upstanding central tube 11. Within thetub 10 is located a foraminous receptacle 12 having a tube 14 receivingthe tube 11 of the tub 10, there being a space between the tubes 14 and11.

A plunger 15 is mounted for reciprocation in the tube 11 of the tub 10,a cross head 16 being connected at 29, or otherwise, to the upper end ofthe plunger. Depending brackets 17 are connected by nuts 18 to the crosshead 16 and extend downwardly between the tube 11 of the tub 10 and thetube 14 of the receptacle 12. At their lower ends, the brackets 17 areequipped with lateral arms 19 extended beneath the bottom of thereceptacle 12, so that when the plunger 15 is pulled upwardly, theforaminous receptacle 12 will be raised. The upper end of a pitman 20 ispivoted tothe lower end of the plunger 15, the lower end of the pitmanbeing pivoted eccentrically to a crank disk 21 on a shaft 22 carried bya bearing 23 on the base 3, suitable gearing 24 being provided, wherebythe shaft 22 may be rotated at the desired speed from a prime mover suchas an electric motor (not shown).

An annular pressure plate 25 is disposed in the foraminous receptacle 12about the tube 14 of the receptacle. An annular abutment plate 26 islocated in the tub 10, about the tube way 11 of the tub. Compressionsprings 27 are secured to the pressure plate and to the abutment plate26, the abutment plate 26 being located in contact with a cover 28 forthe tub, the cover being held down by the retainers 7.

In practical operation, when the shaft 22 is rotated. the crank disk 21and the pitman 2O impart vertical reciprocation to the plunger 15, thebrackets 17-19 causing the foraminous receptacle 12 to reciprocatewithin the tub 10. \Vhen the receptacle 15 moves upwardly, the pressureplate 25, being sustained yieldably by the springs 27, presses the waterout of the garments into the receptacle 12. through the perforations inthe I receptacle 12. The clot-hes are lifted out of the water in thetub, and, at the same time, the water in the garments is pressed out ofthem and the result is a better circulation of .water through thegarments, and an unusually efiicient cleaning of the garments.

Having thus described the invention, what is claimed is 1. In a deviceof the class described, a tub provided in its bottom with an n standingtube disposed approximately in t e axis of the tub, a foraminousreceptacle mounted for reciprocation in the tub and provided in itsbottom with an upstandin tube located about the tube of the tub, aphlnger' located in the tube of the tub, a cross head mounted on theupper end of the plunger, angular brackets connected at their upper endsto the cross head, the brackets extending downwardl between the tubes,and being prolonged between the bottom of the tub and the bottom of thereceptacle, means for imparting reciprocation to the plunger, an annularpressure member located in the receptacle 1 about the tube ofthereceptacle, and spring means cooperating with the pressure mem her toresist the upward movement of the pressure member yieldably.

2. In a device of the class described, a tub provided in its bottom withan upstanding tube disposed approximately in the axis of the tub, aforaminous receptacle mounted for reciprocation in the tub and providedin its bottom with an upstanding tube located about thetube of the tub,an annular pressure member located within the receptacle and disposedabout the tube of the receptacle, spring means for resisting the upwardmovement of the pressure member,

a plun er mounted to reciprocate in the tube 0 the tub, means forimparting reciprocation to the plunger, and means for connecting theupper end of the plunger with the receptacle.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signas ture 1n the presence of two witnesses.
